What roof pitches will this kit fit?

I bought this yesterday. It's for up to a 6 over 12 pitch. They have one for 6/12 to 12/12 but it's not in this kit. It doesn't say anywhere on the box what pitch you are getting (nice). The store had a 6 -12/12 flashing there but not in the kit. None of the other stuff in this kit was sold individually so i was stuck taking my chances and lost. My pitch is a 7/12 so i am going to try to nibble a little off the top rear to try to keep the pipe plumb. If that fails i'll have to go back and get the steeper flashing.
